GENERAL DESCRIPTION
The LINCGUN
®
PROMIG
™
UD Amps guns have been designed to meet IEC
60974-7 specification for welding with steel electrode using the GMAW
(gas metal arc welding) and gas-shielded FCAW (flux-cored arc welding)
processes. LINCGUN
®
PROMIG
™
UD guns are manually guided and air
cooled or water cooled (models with “W”).
The LG PROMIG UD models feature Up/Down and Cross-Switch functions
which allows to adjust welding parameters from the gun. This functionality
is available to LINCON ELECTRIC machines with 12 pin plug.
For the best performance is recommended to use these guns with the
complete Lincoln Electric solution: welders, coolers and FREEZCOOL.
Please always use the original wear parts.
DESCRIPTION OF OPERATION
The supplied welding gun has module 2-button module (Up/Down) already installed. It can be easily changed to a Cross-Switch module which is added to the box.
Up/Down functionality
Up/Down module allows to adjust Wire Feeding Speed (WFS). Pressing the upper button will increase the speed to the maximum, pressing the lower
button will decrease it, accordingly to the wire feeder parameters regulation.
In all configurations other than “Disable Joystick” chosen on the welding machine, Up/Down module will adjust the wire feed speed while welding and
while not welding.
Cross-Switch functionality
The Cross Switch module allows you to switch between different welding modes (left and right buttons) and to adjust WFS (top and lower button).
WFS adjustment can be done all the time: while welding and not welding.
By using a Cross Switch module it can be chosen one of the adjustment options as below:
1. Wire Feeding Speed and Arc Length / Trim
2. Wire Feeding Speed and Job
3. Wire Feeding Speed and Procedure A-B
